论文摘要
我介绍了$ n_c = 3-5 $颜色和$ n_f = 2 $变性的费米子的拓扑敏感性$χ_t$ in $ su（n_c）$ gauge理论的计算。当用组合$ n_c m_ {ps}^2 t_0 $表示$ m_ {ps} $的组合时，结果在于公共曲线上。 $χ_t$随着伪内质量变大而接近其淬灭的价值。晶格模拟使用三叶草费米子。它们是在单个晶格间距上完成的，在$ N_C $中大致匹配，并且在限制的费米昂群体中进行了匹配。
I present a calculation of the topological susceptibility $χ_T$ in $SU(N_c)$ gauge theory with $N_c=3-5$ colors and $N_f=2$ degenerate flavors of fermions. The results lie on a common curve when expressed in terms of the combination $N_c m_{PS}^2 t_0$ where $m_{PS}$ is the pseudoscalar meson mass and $t_0$ is the flow parameter. $χ_T$ approaches its quenched value as the pseudoscalar mass becomes large. The lattice simulations use clover fermions. They are done at a single lattice spacing, roughly matched across $N_c$, and over a restricted range of fermion masses.
